Generate cryptographic hashes from text or files. Everything runs in your browser — nothing is uploaded.
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text or files instantly. All computation runs in your browser — nothing is uploaded.
A: A hash function converts any input into a fixed-length string (the digest). The same input always produces the same hash, but the process is one-way — you cannot reverse a hash back to the original.
A: MD5 is cryptographically broken and should not be used for security purposes like password storage or digital signatures. It is still useful for checksums and non-security file verification.
A: Use SHA-256 or SHA-512 for security-sensitive applications. SHA-256 is the most widely used. MD5 and SHA-1 are only suitable for non-security checksums.
A: Yes — click the file upload zone to select any file and hash its raw bytes. This is useful for verifying download integrity.
A: No. All hashing runs entirely in your browser using the Web Crypto API and a local MD5 implementation. Your data never leaves your device.
